LOGGlNG-SLEIGH BOLSTER.

SPECIFICATION forming part of Letters Patent No. 371,273, dated October11, 1887.

Application filed MarchA, 1887.

.To all whom it may concern.-

Be it known that I, ALBERT O. MOKENDREE, a citizen of the United States,residing at Oonneaut, in the county of Ashtabula and State of Ohio, haveinvented certain new and useful Improvements in Logging-Sleigh Bolsters;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being badto the accompanying drawings, and to the letters of reference markedthereon, forming part of this specification.

My invention consists in the improvements in logging-sleigh bolstershereinafter set forth and explained in the specification and claims, andillustrated in the accompanying drawings, in which Figure 1 shows alogging'sleigh with my improved bolster thereon in perspective. Fig. 2shows a top or plan view of my improved bolster. H

Like letters refer to like parts in both the figures.

In the construction of my improvement shown the runners G and G and thefront crosspiece, H, are of usual and ordinary construction. Thebolster, however, I construct of two pieces, A A, and the central piece,13. This central piece, B, is of about one-third of the length of thepieces A A, and is secured between them by the bolts b b. The portion Bof the bolster also projects somewhat above the side pieces, A A, sothat the log will rest upon it and not upon the pieces A A. Some littledistance from the ends of the central portion, B, I insert rods 0 0through the side pieces, A A. These rods 0 0 project out in front of thesection A of the bolster, so that the log-chain can be looped aroundthem to fasten it when desired. Near one end of the bolster I put in ashaft,'I, having a claw, J, adapted to slip over and catch upon a chainbetween the links thereof, by means whereof the chain can be Woundaround the shaft I to tighten it. This shaft I is provided on one endwith a ratchet-wheel, E, upon which a small dog, e, operates to preventthe shaft I from turning back. In front of the ratchet wheel E, I placeprojecting pins F, between which a handspike can be inserted to turn theshaft I to wind a chain around it. If desired, I can place this deviceat each end of Serial No. 229,736. (No model.)

the bolster; but in practice I find that the shaft and ratchet at oneend of the bolster is ordinarily sufficient for all practical purposes.

I secure this bolster, constructed as aforesaid, to the blocks D D bymeans of bolts a, and I then secure the blocks D D to the runners G andG by means of bolts d, so that a skid may be laid on the blocks D Dbetween the ends of the sides A A of the bolster when necessary to rolla log upon the bolster.

In operation the log rests upon the central piece, B, of the bolster,and the chain is fastened to one of the rods, 0, and passed over the logand under the other rod, O, to the ratchet-shaft I, by means whereof itis drawn tightly around the log, holding it in place. If, however, thechain is used to draw the sled or boat by, then the end, instead ofbeing tightened by the ratchetshaft I, is passed through the hole It inthe front cross-piece, H, and the team hitched thereto, when the strainexerted by the team tends to tighten the chain about the log and keep ittight while the log is being drawn on the sled or boat.

Having thus fully described my invention so as to enable others toconstruct and use the same, what I claim as new, and desire to secure byLetters Patent of the United States, 1s

1. The combination, in a loggingsleigh bolster, of the side sections, AA, and the central section, B, with the rods 0 O, passing through theside sections, A A, and projecting out in front of the section A,substantially as and for the purpose set forth.

2. The combination, in a logging-sleigh bolster, of the side sections, AA, the central section, B, and theprojecting rods 0 C, with the shaft I,provided with a catch or claw, J, and the ratchet E and dog a,substantially as and for the purpose set forth.

3. The combination, in a logging-sleigh bolster, of the side sections,AA, and the central section, B, with the supporting-blocks D D,substantially as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

ALBERT O. MOKENDREE.
